Product details
Overview
TSV624AIPT from STMicroelectronics is a quad rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, low-voltage operation in battery-powered systems. It delivers 420 kHz gain bandwidth at 29 µA supply current per amplifier, operates from 1.5 V to 5.5 V, features 800 µV max input offset voltage (A-grade), and supports stable unity-gain operation with up to 100 pF capacitive load - ideal for sensor signal conditioning in portable medical devices.
For engineers reviewing the TSV624AIPT datasheet, TSV624AIPT pinout, TSV624AIPT application, or TSV624AIPT equivalent, key selection criteria include its guaranteed 0.12 V/µs min slew rate, 1 pA typical input bias current, EMI-hardened performance (92 dB EMIRR at 1.8 GHz), and shutdown capability enabling <5 nA quiescent current per channel in disabled state.
Technical Context
The TSV624AIPT employs complementary PMOS/NMOS input stages to achieve true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and rail-to-rail output swing (within 35 mV of rails into 10 kΩ). Its internal current-starved architecture tightly constrains supply current dispersion (±17% around 29 µA typ), directly stabilizing GBP, slew rate, and open-loop gain across process and temperature.
It integrates four independent amplifiers in one die with no shared shutdown control - unlike TSV623A/TSV625A, the TSV624A variant lacks dedicated SHDN pins and remains always-on. Its unity-gain stability up to 100 pF is achieved without external compensation, and its EMI hardening targets RF immunity in noisy portable environments (400–2400 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct use with single-cell Li-ion (3.0–4.2 V), alkaline (1.5 V), or regulated 3.3 V/5 V rails without level-shifting. |
| Quiescent Current per Amp | 29 µA typ (5 V) - allows >1-year battery life in continuous-sensing applications powered by CR2032 coin cells (220 mAh). |
| Gain Bandwidth Product | 420 kHz typ (5 V) - supports DC-coupled biosignal amplification (ECG, EEG) and anti-aliasing filtering up to ~40 kHz. |
| Input Offset Voltage | 800 µV max (A version) - ensures ≤0.8 mV error in 1× instrumentation amplifier front-ends measuring µV-level sensor outputs. |
| Input Bias Current | 1 pA typ - preserves high-impedance sensor node integrity (e.g., pH electrodes, piezoresistive bridges) without loading errors. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band interference in wearable health monitors operating near GSM/UMTS/LTE antennas. |
| Capacitive Load Drive | Stable with ≤100 pF - permits direct connection to ADC input capacitors or long PCB traces without phase-margin degradation. |
Pinout & Package
TSSOP16 package: 5 mm × 4.4 mm × 1.05 mm body, 0.65 mm pitch, 16-pin thin shrink small outline package with exposed pad (not electrically connected), RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | Inverting Input (−) of Amp A/B/C/D | Differential input nodes accepting signals down to VCC− −0.1 V; high impedance (1 pA bias) minimizes loading on passive filters. |
| 2, 4, 6, 13 | Non-inverting Input (+) of Amp A/B/C/D | Rail-to-rail common-mode range enables direct interfacing with resistive sensors tied to VCC or ground reference points. |
| 7, 8, 10, 15 | Output of Amp A/B/C/D | Drives loads within 35 mV of VCC or VCC−; capable of ±40 mA short-circuit current but rated for 10 kΩ minimum load. |
| 9 | VCC+ | Positive supply pin - requires local 10 nF ceramic decoupling to GND per ST layout recommendation (Section 4.7). |
| 16 | VCC− | Negative supply / ground reference - must be low-impedance; ties to system GND in single-supply configurations. |
| 11, 14 | No Connect (NC) | Internally unconnected pins - must remain floating; no routing or soldering required per ST mechanical drawing (Fig. 27). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input range extends 0.1 V beyond rails; output swings to within 35 mV of VCC+/VCC− - maximizes dynamic range in 1.8 V or 3.3 V systems. |
| Ultra-low power | 29 µA per amplifier at 5 V - enables integration of four precision amps in space-constrained wearables without thermal derating. |
| A-grade accuracy | 800 µV max Vio over −40°C to +125°C - eliminates need for factory calibration in industrial sensor nodes operating across wide ambient ranges. |
| EMI hardening | 92 dB rejection at 1.8 GHz - prevents RF rectification artifacts in ECG leads near Bluetooth/Wi-Fi transceivers. |
| Unity-gain stable | Guaranteed stable with 100 pF capacitive load - simplifies anti-aliasing filter design without isolation resistors or complex compensation. |
Applications
| Portable ECG Monitor | Wireless Glucose Sensor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV624IPT | Standard grade: 1 mV max Vio (vs. 0.8 mV max for A-version); otherwise identical electrical specs and pinout. | Suitable where ±1 mV offset is acceptable (e.g., non-critical sensor buffering), but not for high-accuracy medical front-ends. | Select TSV624IPT only if cost sensitivity outweighs need for guaranteed 800 µV Vio spec across temperature. |
| MCP6004-E/SL | Higher 1 µA supply current per amp; 1 MHz GBP; no EMI hardening; 3.5 mV max Vio; SOIC-14 package (14-pin vs. TSSOP16). | Acceptable for general-purpose portable logic-level interfacing, but unsuitable for RF-noisy or ultra-low-power (<10 µA/channel) designs. | Choose MCP6004-E/SL only when board space allows SOIC-14 and EMI immunity is not required - not a drop-in replacement. |
Compared with TSV624AIPT, TSV624IPT trades guaranteed low-offset performance for lower cost in non-critical roles, while MCP6004-E/SL offers higher speed at 35× higher power and no RF resilience - making TSV624AIPT uniquely suited for precision, low-power, EMI-prone medical and industrial sensing.

FAQ
Is TSV624AIPT pin-compatible with other TSV62x quad op-amps?
Yes - TSV624AIPT shares identical TSSOP16 pinout with TSV624IPT and TSV625A variants. However, TSV625A includes two SHDN pins (pins 11 and 14), which are NC on TSV624AIPT. Direct substitution is safe only if shutdown functionality is unused or externally managed.
What is the maximum capacitive load the TSV624AIPT can drive without oscillation?
The TSV624AIPT is unity-gain stable with up to 100 pF capacitive load, as verified in ST's datasheet (Table 4–7, Section 4.6). Driving >100 pF requires a series resistor (e.g., 10–100 Ω) between output and load, with bench validation recommended per Figure 22.
Does TSV624AIPT support true single-supply operation down to 1.5 V?
Yes - it operates from 1.5 V to 5.5 V with full rail-to-rail input/output swing and specified performance (e.g., 420 kHz GBP, 29 µA ICC) validated at 1.8 V, 3.3 V, and 5 V. At 1.5 V, parameters shift slightly but remain functional per Figures 2–4 and Section 4.1.
How does the EMI hardening in TSV624AIPT improve system-level robustness?
Its EMI rejection ratio reaches 92 dB at 1.8 GHz, meaning 100 mVrms RF interference induces only ~8 µV of rectified offset at the output - preventing false triggers in ECG R-wave detection or erroneous glucose readings in cellular-enabled wearables.
